I was on interstate 5 on may 25, 2009 (memorial day) at the speed of 75-80 mph with my whole family in the car. the car's model is lexus rx330,2006 model. while i was driving on the leftmost lane, my left wheel went a little bit on the rumble strip. i tried to pull my car back on the lane. it is here that the problem started. my steering started to shake and vibrate and the car stopped to accelerate. when all the cars were going at such a high speed there was nothing i could do. i was unable to steer the car as well as accelerate or even brake for quite a while. then i tried braking many times and could finally park the car in the emergency in the left lane shoulder. after that we tried calling all the numbers given in the lexus handbook but no one picked up the phone to help us. after waiting for half an hour or so, my husband collected all his guts and drove the car to nearest gas station. we check the tires and all the pressures etc. but everything looked fine. *tr
